I can relate to this story because I grew up in a farmhouse and witnessed stuffs and then, the community would come out at the beginning of every farming season to offer sacrifices to the gods. There is the new yam festival, corn celebration etc and we all could produce food.

Our land are no longer fertile , we are exclusively depend on northern nigeria for food...

That may or may not be the case, but your contribution is spot on.
Thanks and stay awesome!
